SSD
What is Solid State Drive (SSD)?
SSD, namely Solid State Drive, is a revolutionary storage device. It comprises NAND flash and other components, which are quite different from the traditional hard disk drive. Its advantages are obvious. It has extremely fast speed, which can make the system start and program loading completed in an instant. Moreover, it is quiet without any noise from the mechanical hard drive. It also has good shock resistance, which strongly guarantees data security. Because of this, SSD is widely used in various computer systems and has become a key component to improve system performance.
What is difference between with SSD & HDD?
SSD (Solid State Drives) is made of NAND Flash, controller chip, DDR and other semiconductor materials, which are pasted on the PCB board through the patch process, no mechanical parts, high speed, low latency, low power consumption, quiet.
HDD (Hard Disk Drives) is based on magnetic spinning platters, a technology that has been in use since the mid- 1950s. The data is written to and read from these spinning platters or disks via moving heads. HDDs are mechanical devices with many moving parts and are more prone to mechanical failures and failures due to environmental conditions such as heat, cold, shock and vibration.
How do I know the exact capacity?(SSD)
The capacity is shown in "Megabyte" (same with Hard Disk Drive, 1MB = 1000KB). In Windows environment or DOS mode, 1MB equals to 1024 KB. Therefore 1GB is approximate 953MB.
The actual available memory on the device is less than what is listed on the package. This is due to small discrepancies in file format and algorithms used by various operating systems. In addition, a portion of memory space is reserved for system files and data sectors for better performance.
Can I transfer data or OS from an existing HDD to a new SSD?
Yes. Walram SSD drives in upgrade kits that include all the necessary items required to replace a notebook or desktop HDD with a Walram SSD, including software to easily transfer the OS and important data. Please note that SSD-only SKUs do not include the software. If you need to clone your HDD to a new SSD you will need the bundle kit.
My SSD is a SATA 3 drive and my motherboard only supports SATA 2. Will my SSD work with my motherboard?
Yes, it is backwards compatible, but it will be running your motherboard’s SATA 2 rated speeds.
What the “S.M.A.R.T” is?
S.M.A.R.T stands for “Self-Monitor And Report Technology”, is built in hard drives and solid-state drives to indicate condition of drives. All Walram SSD series support S.M.A.R.T. The S.M.A.R.T contains Average P/E Cycle Count, Total Power-on Time, Power-on Cycle Count, Total Host Writes/Read and other specific information.
Memory Card
How can I determine if a CF card is in Fixed Disk Mode or Removable Disk Mode?
When the CF card is accessed using IDE or SATA through an adapter or extension board, if the CF card is displayed as a local disk, it is in Fixed Disk Mode. If it is displayed as a removable disk, it is in Removable Disk Mode.
Why does my camera stop video recording despite enough remaining storage on the card?
1. Ensure that the video recording time limit is set, not a fixed duration.
2. If the card format is FAT32, recording stops when it reaches 4GB due to file size limitations. Switching the card format to NTFS or exFAT, if supported, can resolve this issue.
Why does the capacity of the memory card displayed on the computer always appear lower than the actual capacity?
The capacity of a memory card displayed on the computer might appear lower than its actual capacity due to various factors such as file system overhead, formatting, and marketing practices. File systems like FAT32 or exFAT reserve a portion of the storage for file allocation tables and metadata, reducing the usable capacity. Additionally, marketing conventions often use decimal-based calculations (1GB = 1,000,000,000 bytes) while computers use binary-based calculations (1GB = 1,073,741,824 bytes), further contributing to the perceived difference in capacity.
How do I choose the right memory card for my requirements?
To select the right memory card:
1. Check compatibility with your device.
2. Choose an appropriate capacity and speed class.
3. Ensure compatibility with your device's file system.
What is the difference between CF card/ CFast card and CFexpress card
CF cards are older and slower, typically used in older devices. CFast cards are faster and more compact, suitable for professional cameras. CFexpress cards offer the highest speeds and capacities, ideal for demanding applications in modern devices.
CFast cannot be formatted on the Canon 1DX Mark 2.
CFast cannot be formatted on Canon 1DX Mark 2 due to a camera-specific bug. This issue also affects CFast cards from other brands. Formatting may be necessary using an adapter board.
DDR RAM
Is ECC memory compatible with a standard motherboard?
ECC memory can be used on a standard motherboard, but the ECC function will be disabled, causing it to operate as non-ECC memory. However, compatibility varies, and on some motherboards, using ECC memory may result in instability or boot issues. Always check your motherboard's specifications to ensure compatibility.
What is Rank?
"Rank" refers to a set of DRAM chips connected to the same chip select line and can be accessed simultaneously by the memory controller. Each rank has a width of 64 bits (72 bits for ECC memory). The concept of rank is determined by the memory controller and DRAM chip specifications, rather than the number of chips on the module. Ranks are independent of whether the memory module is single-sided or double-sided. For instance, eight 8-bit DRAM chips or four 16-bit DRAM chips can form one rank. A rank is essentially a unique, independently addressable 64-bit data area within a memory module, as defined by JEDEC standards.
Is the lighting control software for RGB memory compatible with the motherboard?
Currently, Walram RGB memory supports the lighting control software of four major motherboard manufacturers. We recommend consulting third-party customer service to confirm software compatibility if you wish to use additional RGB control software.
What is XMP?
Extreme Memory Profile (XMP) is a technology designed to enable the overclocking feature of compatible DDR3 or DDR4 RAM, allowing for enhanced performance beyond standard specifications.
What is the performance difference between memory timing and CAS latency (CL)?
Higher memory timings generally result in better performance, while lower CAS latency (CL) is preferred for improved efficiency. Overclocking can further enhance performance, but it's crucial to consider both memory timings and CAS latency. Normal users may opt for RAM with higher memory timings while overclocking enthusiasts should carefully evaluate both memory timings and CL. However, RAM with overclocking features tends to be more expensive.
What is Serial Presence Detect (SPD)？
SPD is a standardized mechanism used in modern computer memory modules (DIMMs) to provide essential information about the module to the system BIOS. This information includes details such as the module's manufacturer, capacity, speed, voltage requirements, and supported memory timings. SPD is stored in a small EEPROM (Electrically Erasable Programmable Read-Only Memory) chip on the memory module itself. When the system boots up, the BIOS reads the SPD data to automatically configure memory settings, ensuring optimal compatibility and performance without the need for manual intervention.
Why does the system only detect half of the installed memory?
Some older version motherboards may not support newer memory modules, resulting in the system being unable to detect the correct memory capacity.
Is DDR4 2400MT/s RDIMM backwards compatible with DDR4 2133MT/s platforms?
Yes. In most cases, DDR4 2400MT/s modules are compatible with platforms designed for 2133. However, the maximum speed of the module is only 2133MT/s.
